Ubuntu Constant Reboot Error

mup.sus error post, a dual boot system is great to have on many levels. Recently, my Linux box running Ubuntu 10.04 ran into problems booting, sending it into a constant reboot loop. After doing some research, I learned that the problem pertained to the update that was applied to the bootloader GRUB. A bootloader is basically the section of code that loads a particular operating system.
Now came the fun part where I had to figure out how to fix the problem. Fortunately, I came across the answer. Use the following information after booting in via a Live Disc.
** SDA1 should be switched with the location of the hard drive where your Linux distribution is installed. This can be found by going to opening Disk Utility.
sudo mkdir /media/win
sudo mount /dev/sda1 /media/win
sudo mount -o loop /media/win/ubuntu/disks/root.disk /mnt
sudo cp /mnt/boot/grub/grub.cfg /mnt/boot/grub/grub.cfg.copy
sudo chmod +w /mnt/boot/grub/grub.cfg
gksu gedit /mnt/boot/grub/grub.cfg
Remove all lines in the file from the start of the file up to, but not including, the following menuentry
### BEGIN /etc/grub.d/10_lupin ###
Reboot into your Linux box and all should be repaired. Until next time …
